[5] Except for an interrupted period due to World War II, Miyazato learned from Miyagi continuously until the death of the latter in 1953.
Since that time, Miyazato, except for a short period during the war, trained continuously with Miyagi until his death.
Miyazato was also a judo instructor: a discipline that Miyagi himself invited him to cultivate as it was complementary to Goju Ryu Karate.
[3] After Miyagi's death (1953), the family communicated that the founder of the style wanted Eiichi Miyazato to succeed him.
The Goju Ryu committee (formed by its major students) at a meeting in February 1954 voted almost unanimously Eiichi Miyazato as the official successor to Chojun Miyagi.
[8] On March 20, 1988, the Okinawa Goju-ryu Karate-do Kyokai awarded him the rank of 10th dan in karate.
[3] Miyazato's students included Teruo Chinen, Morio Higaonna, Masaji Taira, Ronald Michio Yamanaka and Mike Clarke.
